LAURENCE S. LACHHAN, @F NEW YORK, N. Y.

Application filed August 24, 1928. Serial No. 659,045.

T 0 all whom it may concern:

Be it known that "l, LAURENCE S. LACE- MAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented "certain new and useful Improvements in Reels, of which the following is a specification. 7

My invention relates to the'construction of reels composed mainly of metal rods or wires and designed for holding moving picture films or other ribbons or lengths of material wound upon the portion of said reel constituting the drum proper thereof.

The object of my invention is to simplify and cheapen the construction of reels or similar structures by employing for the main elements thereof lengths or pieces of metal wire or metal rod welded up together to make the complete reel.

A further object of my invention is to so construct the reel that itwill afiord a convenient means forsecuring the inner end of the moving picture film or other ribbon to the hub or drum without employing supple mental clips or other devices for fastening I the ends of the ribbon or film to the drum.

To these ends my invention consists in the novel construction of reel as hereinafter moreparticularly described and claimed and comprising mainly end members each consisting of a metal ring and radiating wire elements welded thereto and to a suitable center and a drum part composed of metal rods end-welded to the insides of said radiating wire elements.

in the preferred manner of carrying out invention the wires or rods so end-welded are employed in pairs slightly separated from one another, both members of each pair being welded preferably to the side of the same radiating Wire element.

in the accompanying drawings:

Fig. 1 is an end elevation of one form of a reel constructed in accordance with my invention.

Fig. 2 is an end elevation of the central portion thereof enlarged.

Fig. 3 is a plan in which radiating wire elements, occupying a vertical position in the Fig. 2, are shown in cross-section.

Fig. 4 is a vertical section on the line H of Fi 2. V

Fig. 5 illustrates the manner in which the wires constituting the drum proper may be secured to the radiating wire elements or spokes.

Fig. 6 illustrates a modification of the invention.

Each end element of the reel comprises a wire ring 1 and the radiating wires or spokes 2 which radiate from a hub disk or center 3 to which said wires 2 are welded as illustrated more particularly in Fig. 4, although they may be welded or secured thereto in other ways without departing from my invention.

In the particular form of the invention illustrated in the drawings said wires 2 are side-welded at their ends against a flange 3 of the center or disk 3, the latter constituting the hub disk which in turn may be directly welded to or secured against the end of a hub barrel 4 adapted to carry the spindle or shalt upon which the reel is mounted.

The particular manner of mounting the hub barrel 4 on the spindle forms, however, no special part of my invention and will not therefore be described.

The outer ends of thespoke elements 2 may be welded to the rings 1 in any desired way but preferably in'the manner described in the joint application of myself and Edward Fulda filed Feb. 28, 1922, Serial No. 539,899, by overlapping the end of the rod upon the side of the ring and applying premure while the parts are heated by a heating current passing from one to the other and crowding them, by pressure applied sidewise, into the.same plane while they are held against displacement with relation to one another.

The drum. which receives the film, ribbon or other object to be wound up upon the reel, consists or wire rods 5. These are disposed in the circumference of a circle and end-welded in position between the spokes 2 embodied in the two end elements respectively of the reel. Said rods or wires 5 ice are preferably employed in pairs, as illustrated, and are slightly separated from one another to afiord spaces into which the end of the film or ribbon may he slipped, so

that it will be held when the film or ribbon 1105 is wound upon the'reel. By this means I I diipense with the use of special clips.

n the drawings the space. between the pairs of rods 5 is shown somewhat exaggerated. In practice the space would vary no wherein a pair of said rods 5 is shown mounted in grooves 6 in a suitable blocker holder 7 and thereby held against spreading apart under the action of pressure applied to the elements 2 in the welding operation.

The block 7 may be so constituted as to form one-of the electrodes of the electric welding device, the opposite electrode or pressure block which applies current to the element 2 being indicated at 8.

The effect of crowding the element 2 into the space between the rods 5, 5 when the parts are heated by the electric resistance method, is to form'a weld the bur of which will be located mainly in the space between the air of rods 5, 5. To assist in thus partially concealing or masking the bur so that it may not tear the film, the ends of the rods 5 are reduced or tapered, as indicated, on their sides nearest one another, the tapering being if desired alsoextended to the outside so that there shall be no sharp corners to tear the hands of the operator or to mutilate the film.

By the use of the holder 7, such as ,indicated, uniform separation of the double members 5 is secured and, by uniformly spacing the radiating members 2, it will be obvious that a windingdrum re lar in form circumferentiall can be obta1ned.

Furthermore, as wil be obvious, by the use of the holders or blocks 7 uniformly disposed in the circumference of a circle and sufficient in number to accommodate all the pairs of rods 5 that are employed to make up the reel, the securing of each endmember to all of the rods or pieces 5 may be produced by one operation. After welding the wires or elements 5 at one end to one of the end members, the other end element may "be secured to the opposite end of said rods in a similar manner, the block 7 being suitably formed to accommodate the previously welded elementsi2 during the operation.

Instead of using pairs of rods 5 it is obvious that sin le rods may be employed, as indicated in ig. 6, each being at its end directly against the side of a radiating wire element 2.

What I claim as myinvention is 1. A reel comprising two side memibe each consisting of a wire ring, a center and radiating wire spokes or elements arranged in the plane of the ring and welded thereto and to the center and a winding drum consisting of metal rods welded at their ends to the inside of the radiating wires of the side elements respectively.

2. A wire reel comprising side members each consisting of a wire ring, a center and connecting radiatin wire elements welded to the ring and to the center and a windin drum composed of pairs of rods end-welded to the radiating wires of the side members.

3. A wire reel comprising two side members each consisting of a wire ring, wire spokes and center welded together and a drum comprising pairs of metal rods slightly separated from one another and welded in pairs .at their ends to the inside ofthe radiating wires of the side members.

welded I 4. A metal reel consisting of wire rings,
